Scientists claim that climate change is happening because Earth is warming. They also claim that humans have helped cause the wa

rming by adding greenhouse gases to the atmosphere. Other people claim that Earth is not experiencing climate change because some winter days are still very cold. Use evidence to evaluate each claim about climate change.

Answer:

There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.

Answer:

I belive we are in climate change each year the earth gets closer to the sun and pollution from cars and factories cause the earth to warm up and cause pollution in our air.  plastic is in the ocean, ice caps are melting, and the ocean is rising climate change is alredy here.

Mass of water 50.003 g 24 95C Temperature of water Specific heat capacity for water 4.184J/g C Mass of metal 3.546 Temperature o
Norma-Jean [14]

Correct Question :

Mass of water = 50.003g

Temperature of water= 24.95C

Specific heat capacity for water = 4.184J/g C

Mass of metal = 63.546 g

Temperature of metal 99.95°C

Specific heat capacity for metal ?

Final temperature = 32.80°C

In an experiment to determine the specific heat of a metal student transferred a sample of the metal that was heated in boiling water into room temperature water in an insulated cup. The student recorded the temperature of the water after thermal equilibrium was reached. The data we shown in the table above. Based on the data, what is the calculated heat absorbed by the water reported with the appropriate number of significant figures?

Answer:

1642 J

Explanation:

Given:

Mass of water = 50.003g

Temperature of water= 24.95C

Specific heat capacity for water = 4.184J/g C

Mass of metal = 63.546 g

Temperature of metal 99.95°C

Specific heat capacity for metal ?

Final temperature = 32.80° C

To calculate the heat absorbed by water, Q, let's use the formula :

Q = ∆T * mass of water * specific heat

Where ∆T = 32.80°C - 24.95°C = 7.85°C

Therefore,

Q= 7.85 * 50.003 * 4.184

Q = 1642.32 J

≈ 1642 J

Balance the equations by inserting coefficients as needed.<br> CaH₂ + H₂O Ca(OH)₂ + H₂
dmitriy555 [2]

The balanced equation is CaH_{2}  + 2 H_{2} O = Ca(OH)_{2}  + 2 H_{2}.

The above equation is a redox reaction. A chemical equation is said to be balanced when the total mass of atoms on the reactant and product side are equal. This means that the number of atoms on both side must also be equal.

We have, CaH_{2}  + H_{2} O = Ca(OH)_{2}  +  H_{2}.

The number of atoms of Calcium (one on both sides) and Hydrogen(four on both sides) are equal. Whereas, there are 2 atoms of Oxygen on the right-hand side and only  1 atom of Oxygen on the left-hand side. So, we can put the coefficient of 2 on the molecule that has Oxygen on the left-hand side to balance them out. i.e.,

CaH_{2}  + 2H_{2} O = Ca(OH)_{2}  +  H_{2}

Now, there are 6 atoms of Hydrogen on the left-hand side but only 4 on the right-hand side. To balance this, we can put the coefficient of 2 on the Hydrogen molecule on the right-hand side.

Thus, we get the final balanced equation as :CaH_{2}  + 2 H_{2} O = Ca(OH)_{2}  + 2 H_{2}

The elements of a delta Hf of ___ kj\mole at standard temp and pressure
EastWind [94]

<u>Answer:</u>

<em>One mole of a substance forms Instead of standard atmospheric pressure and temperature from its pure elements{ conditions being the same} then this change and enthalpy is known as </em><em>enthalpy of formation.</em>

<u>Explanation:</u>

The equation of this formation can let us know what actually happens

ΔH = ΔHf(products) - ΔHf (reactants)

Hence we can say this change in enthalpy formation is the difference between the sum of product and sum of reactants.

Explain the law of conservation of energy. Give a specific example using kinetic and potential energy that shows how energy is c
Marrrta [24]

Answer:

The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. This law is taught in physical science and physics classes in middle schools and high schools, and is used in those classes as well as in chemistry classes. When playing pool, the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.

Water take a (long/short) time to heat up due to it's High Specific Heat.
7nadin3 [17]
Because of water's specific heat capacity, it takes longer for the water to heat up. This is useful because if water heated up quickly, then the ocean would be literally boiling, and it would evaporate into the atmosphere.
